Why Is Miley Cyrus So Skinny?

Miley Cyrus has slimmed way down in recent months thanks to her devotion to pilates — the 19-year-old star practices six times a week at an L.A. studio — and an allergy to gluten and lactose. When reports came out attributing Miley’s skinny physique to an eating disorder, the actress/singer took to Twitter to refute the speculative stories. “For everyone calling me anorexic, I have a gluten and lactose allergy,” she wrote. “It’s not about weight it’s about health. Gluten is crapppp anyway!”
